GridPlus Lattice1 SDK

WARNING: This is early alpha software and is subject to change. It is recommended that any mainnet usage be restricted to small amounts.

The Grid+ SDK allows any application to establish a connection and interact with a Grid+ Lattice1 device as a remote signer. With the Lattice1 as an extremely secure, connected keystore with signing capabilities, this SDK gives users the following functionality:

• Pair (exchange keys and establish encrypted communication channel) with a user's Lattice1 device using a serial
• Get addresses from the paired device (Bitcoin or Ethereum)
• Request ETH, ERC20, and BTC signatures, which the Lattice1 owner must authorize on the device
• Create a permission giving your app the ability to request automated signatures based on rules accepted by the user
• Request automated signatures against a permission

Documentation

The documentation for this SDK can be found here. There you will find a complete quickstart guide (a shorter version of which is available in the next section) as well as a full API reference and schema enumerations. Please consider that document the source of truth for all things SDK.

Installation and Setup

This SDK is currently only available as a node.js module. You can add it to your project with:

npm install gridplus-sdk

You can then import a new client with:

import { Client } from 'gridplus-sdk';

or, for older style syntax:

const Sdk = require('gridplus-sdk').Client;

Initializing a Client

Once imported, you can initialize your SDK client with a clientConfig object, which at minimum requires the name of your app (name) and a private key with which to sign requests (privKey). The latter is not meant to e.g. hold onto any cryptocurrencies; it is simply a way of maintaining a secure communication channel between the device and your application.

const clientConfig = {
    name: 'MyApp',
    privKey: crypto.randomBytes(32).toString('hex')
}

Adding Providers

To connect the SDK to supported cryptocurrency networks, you will need to add providers to the clientConfig. We have two from which to choose:

import { providers } from `gridplus-sdk`;
const eth = new providers.Ethereum({ 
    network: 'rinkeby' 
    etherscan: true, 
});
const btc = new providers.Bitcoin({
    network: 'test3',
    blockcypher: true,
    coin: 'btc',
});

clientConfig.providers = [ eth, btc ];

Initialize!

With the clientConfig filled out, you can initialize a new SDK object:

const client = new Client({ clientConfig: clientConfig });
client.initialize((err, connections) => { })
